The party, the stunt school/acting group "Action for Hire", are approached by an Acolyte of Candlekeep known as Thaddeus Tozahl. Thaddeus, believing Action for Hire to be an actual adventuring group, does hire the group to head to the Feywild and escort a peculiar case to its next leg of the journey. Thinking it to be another acting gig, the group agrees to the "stunt work".
Once in the Feywild, they are met by a cantankerous eladrin artificer, Radaeas. He quickly figures out the misunderstanding, but accepts their help anyway. The group, however, still believe this to be a full-blown production, and proceed to crew his magic skiff/schoolbus, thinking it'd all be good way to method act.
